Code: J34.2
Description: Deviated nasal septum
Context: This code identifies patients with a structural deviation of the nasal septum that may cause obstruction or breathing issues.

Guidelines for Proper Use

• Structural diagnosis: Use when septal deviation is confirmed by physical exam or imaging.
• Symptomatic or asymptomatic: Can be used whether or not the deviation causes symptoms.
• Commonly found incidentally: Sometimes noted during nasal endoscopy or sinus evaluation.
• Relevant for surgical cases: Used pre- and post-operatively for septoplasty or rhinoplasty documentation.
• Permanent condition: Generally does not change unless surgically corrected.

Common Misuses of J34.2

• Using without confirmation: Should not be applied unless deviation is clinically or radiographically confirmed.
• Coding as acute condition: It is structural, not infectious or acute.
• Overuse for mild curvature: Apply only when deviation has clinical relevance or noted by a physician.
• Omitting related codes: Combine with other sinus or obstruction codes if applicable.

Notes / Documentation Tips

• Describe findings: Note whether deviation is left, right, or S-shaped.
• Include symptoms: Congestion, nasal obstruction, mouth breathing, or snoring.
• Link to procedure: Include in documentation for septoplasty or nasal surgery cases.
• Confirm via exam: Nasal speculum or imaging findings should verify deviation.
• Note clinical impact: Mention if it interferes with airflow or contributes to chronic sinusitis.
